Upham two-color attachment, which will take any two-color work that strikes in 
but not over. Work can not be handled that strikes over, because the plates are 
flat for pre.ss and curved for Upham attachment, the stretch of the curve not 
permitting register. The circumference of the Upham cylinder is only 33 inches 
therefore the largest plate matter which can be puf on the Upham cylinder would 
be 33 inches around the cylinder but the full width across. That is to say, the 
maximum size of the plate matter to be put on the Upham cylinder is 33 x 49. 
All other color work can be handled very well. By working one on press and one 
on attachment two jobs of different colors can be run on the Upham at the same

Direct-Current Electric Service 

SYNCHRONOUS CONVERTERS. 

Nos. 4373, 4374, and 4315 — Application. —Convert 6,600-volt, 3-phase, 25-cycle 
alternating current through 1,600 kilovolt-ampere, self-cooled, oil-insulated 
3-phase, step-down transformers, into 240-volt direct current, the neutral wee 
of the 120/240 volt direct-current 3-wire system being derived in the neutral 
points of the transformer secondary coils. 

Cupacity. —Each converter is rated to carry continously 6,000 amperes at 240 
volts with a rise of 50° C. above the ambient temperature; equal to 1,440 kilo¬ 
watts at unity power factor. Each converter is capable of carrying the entire 
direct-current electric loacl of the Government Printing Office and the Washington 
city post office. 

Distinctive features. —Each converter is classified as shunt wound, booster type, 
with balanced relay control of the auxiliary commiuating field for the purpose 
of automatically adjusting commutation at all points of the load. Each con¬ 
verter is arranged for starting on its alternating-current side and provided with 
solenoid-operated oil switch and two direct-current air-circuit breakers. Motor- 
operated rheostats control the main, liooster, and auxiliary commutating field 
on each converter. Protection against overload, undervoltage, and oversiieeding 
on the direct-current side and overload through induction type, time relays, and 
undervoltage on the alternating-current side of each converter is provided for.

Compressed-Air Service 

AIR COMPRESSORS. 

Nos. 4377, 4378 — Application. —Furnish compressed air, day or night service, 
for operating elevator doors, monotype keyboard and casting machines, agitating 
electrolytic solutions in the platemaking division, air blast under metal melting 
pots, pneumatic control work in testing section, pneumatic tube-carrier service, 
cleaning, and other industrial purposes. The compressors deliver air at 50 pounds 
gauge pressure which is reduced, through appropriate pressure-reducing valves, to 
such operating pressure as required in each application. 

Capacity. —Compressors are rated to deliver 1,250 cubic feet of free air per 
minute at 100 pounds pressure and 250 r. p. m. at full load of 230 brake 
horsepower. 

Distinctive features. —Each compressor is direct connected to a Westinghouse 
140-volt, 3-phase, 25-cycle, 230-horsepower synchronous motor with belt-driven 
exciter. Each compressor is supplied with current through a bank of three 
single-phase 100 kilovolt-ampere Westinghouse transformers with connections 
so arranged, through suitable 3-pole, double-throw transfer switches, whereby 
each motor can be connected to either bank of transformers. Regulation of the 
compressors is accomplished by means of 5-stage automatic clearance control. 
A horizontal tube type after cooler, containing 300 square feet of cooling surface 
is installed in the 8-inch discharge pipes to condense and remove the entrained 
moisture present in the air. 

Manufacturer's rating. —22 and 14 x 14 Class PRE-2; Right-hand air cylinder 
14 X 14; left-hand cylinder 22 x 14; final discharge pressure 100 pounds; 250 
r. p. m. Piston displacement, 1,528 cubic feet per minute. Cubic fent of free air 
actually delivered per minute: At full load 1,250; three-quarter load 938; half 
load 625, the horsepower input being 230, 181.5, and 133.5, respective!v. 

Manufacturer. —Ingersoll-Rand Co., 11 Broadway, New York City. Installed 
by W. G. Cornell Co., Washington, D. C., December 12, 1923. 

Nos. 4599 , 4600 — Application. —Furnish compressed air, night, Sunday, and 
holiday service, for operating elevator doors, Monotype keyboard and casting 
machines, agitating electrolytic solutions in the plate-making division, air blast 
under metal melting pots, pneumatic control work in testing section, j)neumatic 
tube-carrier service, cleaning, and other industrial purposes. The compressors 
deliver air at 50 pounds gauge pressure, which is reduced, through appropriate 
pressure-reducing valves, to such operating pressure as required in each application. 

Capacity. —Each compressor is rated to deliver 290 cubic feet of free air per 
minute at 375 r. p. m. at the full load input of 55 brake horsepower. 

Distinctive features. —Each compressor is direct connected to a General Electric 
Co. 55-horsepower, 50° C., 375 r. p. m., 440-volt, 3-phase, 25-cycle, squirrel-cage 
type induction motor and controlled by means of a General Electric Co. type 
CR-7052 automatic starter and CR-2922 gauge type pressure regulator. Regu¬ 
lation is obtained by means of automatic start and stop electric control, whereby 
the unit automatically stops when a predetermined receiver pressure has been 
reached and automatically starts when the receiver pressure falls to a predeter¬ 
mined point. This requires a centrifugal starting unloader which permits the 
compressor to start under no load. The automatic water valve automatically 
starts and stops the flow of water with the action of the compressor which effecj^s- 
a saving in cooling water during the idle periods in the compressor operation. 

Manufacturer's rating. —Direct connected, vertical, piston displacement 400' 
cubic feet per minute, 50 pounds gauge pressure, type 20, size 12i^ inches diame¬ 
ter by 8-inch stroke, duplex, single acting, single stage. Actual delivery of free 
air at 50 pounds gauge per minute, 290 cubic feet at 375 r. p. m.
